Abstract

A dehumidifier includes a housing, a water tank mounted in the housing, a detection device, and a controller electrically coupled to the detection device. The detection device includes a detector arranged at the housing and a signal trigger arranged in the water tank. The signal trigger is configured to move to a detection area of the detector in response to a water level in the water tank being higher than a preset position, and move out of the detection area of the detector in response to the water level in the water tank being lower than the preset position. The controller is configured to control a pump to stop pumping water in response to the signal trigger being located outside the detection area of the detector.

First claim

What is claimed is:

1. A dehumidifier comprising:
a housing;
a water tank mounted in the housing;
a detection device including:
a detector arranged at the housing; and
a signal trigger arranged in the water tank, the signal trigger including a hollow interior and a water inlet hole communicating the hollow interior and the water tank, and the whole signal trigger being configured to:
move to a detection area of the detector in response to a water level in the water tank being higher than a preset position, and
move out of the detection area of the detector in response to the water level in the water tank being lower than the preset position; and

a controller electrically coupled to the detection device and configured to control a pump to stop pumping water in response to the signal trigger being located outside the detection area of the detector.

2. The dehumidifier of claim 1 , wherein the detector includes a Hall sensor and the signal trigger includes a float with magnetism.

3. The dehumidifier of claim 2 , wherein:
the housing includes a partition plate;
the partition plate and the housing together form a mounting groove;
the water tank is mounted in the mounting groove; and
the detector is mounted at the partition plate.

4. The dehumidifier of claim 3 , wherein a lower end of the partition plate protrudes toward the water tank to form a limiting groove, and the detector is mounted in the limiting groove.

5. The dehumidifier of claim 4 , wherein a bottom of the limiting groove is provided with a heat dissipation through hole.

6. The dehumidifier of claim 4 , wherein an opening of the limiting groove is provided with a limiting buckle clamping a surface of the detector.

7. The dehumidifier of claim 6 , wherein the limiting buckle is one of two limiting buckles provided at the opening of the limiting groove, and the two limiting buckles are arranged at opposite sides of the limiting groove, respectively.

8. The dehumidifier of claim 3 , further comprising:
a compressor;
wherein the housing is divided by the partition plate into two chambers, one of the two chambers forming the mounting groove and the compressor being mounted in another one of the two chambers.

9. The dehumidifier of claim 3 , wherein the water tank is pullable as a drawer.

10. The dehumidifier of claim 1 , wherein:
a limiting chamber extending in a vertical direction is formed at a side wall of the water tank;
a communication port communicating with the water tank is formed at a bottom of the limiting chamber; and
the signal trigger is arranged in the limiting chamber and capable of moving up and down.

11. The dehumidifier of claim 10 , wherein the limiting chamber is integrally formed at the side wall of the water tank.

12. The dehumidifier of claim 10 , wherein the limiting chamber is detachably mounted at the side wall of the water tank.

13. The dehumidifier of claim 10 , wherein a top of the limiting chamber includes a limiting plate configured to stop the signal trigger.

14. The dehumidifier of claim 13 , wherein:
the limiting plate is provided with a buckling groove; and
the side wall of the water tank includes a limiting buckle adapted to the buckling groove.

15. The dehumidifier of claim 10 , wherein:
a fixation member is provided at the bottom of the limiting chamber, and a fixation hole is provided at the fixation member; and
a support base supporting the fixation member is arranged at the water tank, and a fixation post adapted to the fixation hole is arranged at the supporting base.

16. The dehumidifier of claim 10 , wherein a top of the signal trigger is provided with a limiting block configured to abut against a top of the limiting chamber.

17. The dehumidifier of claim 10 , wherein a rib is provided at a periphery of the signal trigger.
